Using my 10x50 i saw Iridium 27 at 05:51:18 18 Jul UTC, it was due east of
my location (54.25N 110.11W 556m) at an altitude of 17 degrees. I was able
to spot it's flashes quite clearly and for a time, Iridium 27 was visible
while it was flashing. I needed my hands to hold the binocs, and swat
mosquitos, so i couldn't time the flashes. The time and track put it as
Iridium 27.
